Microsoft has posted a blog post on the way updates and privacy controls are handled with the new Windows 10 Creators Update. This one is going to save a lot of heartache, a lot of complaints in many forums, and generally fix one of the major complaints with Windows 10.
Prior to the Creators Update, Windows 10 made most of the decisions for you regarding when updates would be installed and didn’t provide ways to tailor the timing to your specific needs. What we heard back most explicitly was that you want more control over when Windows 10 installs updates. We also heard that unexpected reboots are disruptive if they happen at the wrong time.
